I'm struggling with this problem and I need some help with it, please? Confidence Intervals. In Exercises 9–-24, construct the confidence interval estimate ofthe mean. 20. Years in College Listed below are the numbers of years it took for a random sample ofcollege students to earn bachelor's degrees (based on data from the National Center for Educa-tion Statistics). Construct a 95% confidence interval estimate of the mean time required for allcollege students to earn bachelor's degrees. Does it appear that college students typically earnbachelor's degrees in four years? Is there anything about the data that would suggest that theconfidence interval might not be a good result?4 444 444.5 4.5 4.5 4.5 4.5 4.566.899131315

You are opening a plant that will manufacture widgets (w) and gizmos (g). The widget machines cost $10,000 each. They each require 4 operators and 500 square feet o space. The gizmo machines each cost $6,000 ard require 6 operators and 500 square feet of space. Your new plant has 40,000 square feet of space available for the machines. HR estimates that you will be able to hire 460 operators to run the machines. Your budget for buying machines is $660,000. a) List all 5 constraints. b) List the coordinates of the corners of the graph in (g,w) form. (We cannot buy a fraction of a production machine. If the corners are not whole numbers, give the closest whole number coordinates along each constraint line.) c) Given the following estimated profits per hour per machine in each scenario, how many of each type of machine should you buy?
